I'm progressing with my 455 swap and I'm not sure how to proceed with the fuel line. My old 1968 inline 6 has two ports on top of the fuel pump. One from the tank, the other to the carb. The fuel pump on the 455 (from 71 delta) has three ports on the fuel pump. One in, one to the carb, and I assume the other is for a return line to the tank. Am I correct with this assumption? Do I need to run a return line back to the tank? Can I just plug this port? Any help is appreciated.
Thanks.
